Mozilla has started a new initiative called Phones for Apps for Firefox OS that will see the not-for-profit organisation giving free Firefox OS devices to developers in exchange for building apps for the platform.

The organisation announced the free handset deal, which is an extension of its promise to give free devices to developers that attend its developer workshops, in a blog post on Thursday

"Wherever you are, if you can show you've got a great app idea and the skill to build it, we'd love to see your apps in the Marketplace when the Firefox OS launch begins later this summer. And to sweeten the deal, we'll send a Firefox OS Developer Preview device for you to work with now," Havi Hoffman, a curator at Mozilla Labs, wrote.

There are no strict or specific entry requirements to be in the running for a free Geeksphone Keon handset, although Mozilla did say that interested developers will need to move fast as "launch dates are approaching fast" and the supply of Geeksphone handsets is limited.

Ports of apps from other platforms, as well as completely new apps, are eligible for entry in the running to get a free developer handset. In order be in with a chance of getting their hands on one, developers simply need to submit an app proposal to Mozilla.

Mozilla also said that developers that start building for the platform now will also have 'first-mover' advantage in the marketplace when the first retail devices go on sale later in the year.
